Abstract (en)
[origin: US2022311705A1] Techniques for leveraging MLD capabilities at edge nodes of network fabrics to receive SNMAs from silent hosts, and creating unicast addresses from the SNMAs for the silent nodes that are used as secondary matches in a network overlay if primary unicast address lookups fail. The edge nodes described herein may act as snoopers of MLD reports in order to identify the SNMAs of the silent hosts. The edge nodes then forge unicast addresses for the silent hosts that match with the least three bytes of the SNMAs. The forged unicast addresses are presented as unicast MAC/IP mappings in the fabric overlay. In situations where a primary IP address lookup fails, the look-up device performs a secondary lookup for a mapped address that has the last three bytes of the IP address. If a mapping is found, the lookup is sent as a unicast message to the matching MAC address.
